摘要：
An experimental study has been performed of the relative intensity noise (RIN) of a semiconductor laser in optical feedback regimes I to V At low bias current, a low RIN is observed with low feedback ratio, the RIN increased in the coherence collapse regime (regime IV) and decreased in regime V The RIN in regime V is lower than that of the solitary laser. For higher bias current, a higher feedback ratio is needed for the semiconductor laser to transit from regime IV to V The measurements are found to be in good qualitative and quantitative agreement with theoretical predictions.
